Observing Notes
Object Note
Two interacting galaxies, IC819 and IC820 cataloged together as NGC4676, also known as NGC4676B
Harold Corwin
IC 819 and IC 820 are together identical to NGC 4676. Spitaler has the two IC objects as new discoveries about 1m 12s preceding an 8th magnitude star which he identified correctly. He has measured the offsets micrometrically, so we'd expect his resulting positions to be quite good.
However, the actual offsets are 2m 12s preceding the star. Spitaler has either misread his micrometer, or made a transcription error. Once that is corrected, the identity is not in doubt.
